Breast Cancer Misdiagnosis in Ireland

We’ve seen the headlines. Figures released under the Freedom of Information Act show that breast cancer accounts for more than a quarter of all cancer misdiagnosis claims in Ireland. That is not just a number. That is hundreds of women and families whose lives were turned upside down because something important was missed. In some cases, it was an outdated machine. In others, a rushed reading or a system that lacked basic checks like multidisciplinary review or proper follow-up.

The result is always the same. Lost time. Delayed treatment. Anxiety. Grief. And the awful feeling that no one was listening when you raised a concern.

At Crimmins Howard, we meet women and families at these moments. We know what it means to have your instincts ignored or your symptoms brushed aside. Our solicitors have worked with people across Clare, Limerick, Galway and beyond who simply want the truth. We give them space to speak, and we walk them through the legal process with plain English and open communication. No confusion. No pressure. Just clear support from a local firm that believes in fairness and accountability.

If you or a loved one has been affected by a delayed or incorrect breast cancer diagnosis, there is help. There are options. And there is a way forward.

How Breast Cancer Misdiagnosis Happens

Breast cancer misdiagnosis remains one of the most serious forms of medical failure in Ireland. When systems fall short, patients are the ones who suffer—physically, emotionally and financially. Understanding how these errors occur can help individuals recognise if their experience amounts to negligence.

1. Misread Scans and Imaging Errors

• The most common cause of breast cancer misdiagnosis is the incorrect reading of mammograms or ultrasounds.
• Some radiologists fail to detect subtle but important changes in breast tissue, while others mistakenly identify benign findings as cancerous.
• In some instances, a scan is only reviewed by one clinician instead of being double-checked or discussed at a multidisciplinary meeting.

2. Incomplete or Skipped Triple Assessment

• Best practice dictates a three-part evaluation: clinical breast examination, imaging (mammogram or ultrasound), and biopsy.
• When any one of these steps is omitted, diagnostic accuracy drops significantly.
• Some clinics proceed based on imaging alone, leading to missed cancers or false positives.

3. Outdated or Poor-Quality Equipment

• Multiple Irish reports have flagged mammogram machines that were over 15 years old—well beyond their expected lifespan.
• Blurred or low-resolution scans reduce the chances of early detection and can produce misleading results.
• In many cases, the technology failed before the clinician did.

4. Delayed or Inadequate Referrals

• GPs may delay sending a patient to a breast clinic, especially if symptoms are dismissed as hormonal or if the patient is under 35.
• Younger women are often considered low risk, which leads to complacency and missed diagnoses.
• Sometimes, referrals are made but not marked as urgent, resulting in months-long delays.

5. Breakdowns in Internal Communication

• Even when abnormalities are flagged, follow-ups can fall through the cracks due to administrative oversights.
• Consultants may spot issues on a scan, but that information might not be passed on to the patient or the referring doctor.
• Lack of tracking or auditing means that no one realises an error has occurred until it’s too late.

6. False Positives and Unnecessary Treatment

• Some women are wrongly diagnosed with breast cancer and subjected to life-altering treatments such as mastectomies, chemotherapy or radiotherapy.
• These cases are deeply traumatic and medically avoidable.
• A false cancer diagnosis can have long-term physical and psychological consequences even when corrected.

Misdiagnosis is not just the result of one bad call. It often stems from a combination of under-resourced facilities, overworked professionals, poor communication and neglected systems. When that happens, the person affected deserves straight answers, not silence.

Consequences of a Delayed or Incorrect Diagnosis

When a breast cancer diagnosis is delayed or incorrect, the fallout is often severe. The harm is rarely limited to one area of life—it affects health, family, finances, and long-term trust in medical care. Below are the core consequences commonly faced by affected patients in Ireland:

• More invasive treatment: When caught late, breast cancer typically requires more aggressive intervention. What may have been treated with a minor procedure could escalate to mastectomy, extended chemotherapy, or radiotherapy. Patients may lose access to early-stage options that would have preserved more of their health and quality of life.
• Worse prognosis: Delays can allow the cancer to spread to lymph nodes or beyond. The chance of full recovery drops, and long-term survival becomes less certain. In some cases, curative treatment is no longer possible, and care becomes palliative.
• Psychological trauma: Being falsely reassured, only to discover the truth later, often leads to anxiety, shock and deep emotional distress. Many patients feel their instincts were ignored. Others live with the knowledge that critical time was lost, or that treatment was harsher than it needed to be.
• Irreversible treatment from a false positive: In cases of incorrect diagnosis, women have undergone surgery or chemotherapy they didn’t need. These outcomes are physically scarring and psychologically devastating, particularly when reconstruction or fertility is affected.
• Family and carer disruption: Late-stage cancer affects the whole family. Partners may become carers overnight. Children may experience sudden changes in household dynamics. Plans for education, travel, work or care responsibilities are often disrupted.
• Financial stress: Patients may lose income due to prolonged absence from work. They face costs for private follow-ups, transport to hospitals, childminding during treatment, or support services not covered publicly. Many rely on compensation not just for justice—but to stay afloat.
• Loss of trust in medical care: Patients often report reluctance to re-engage with the health system. This can result in missed screenings, delayed follow-ups and ongoing anxiety around future medical advice.

Do I Have a Claim?

Not every delayed diagnosis leads to a valid legal claim—but when mistakes in medical care cause real harm, you may be entitled to pursue compensation. Breast cancer misdiagnosis claims typically arise when the care you received fell below the standard expected of a qualified healthcare professional, and that failure led to worse outcomes than you otherwise would have faced.

To determine whether you have grounds for a claim, the key questions are:

• Was there a clear breach of duty? Medical staff must act in line with accepted clinical standards. If your GP failed to refer you for assessment despite symptoms, or if a radiologist missed a tumour on a scan, this may qualify as negligence.
• Did that failure directly affect your health or treatment? There must be a proven link between the mistake and your outcome. For example, if cancer spread due to a delayed diagnosis and this changed your treatment plan or prognosis, that connection strengthens your case.
• Would another competent doctor have acted differently? Courts assess negligence by asking whether another similarly qualified doctor would have handled things more competently. If they would have referred you, ordered more tests, or identified the cancer earlier, this supports a claim.

If any of the following apply, you may have a strong basis to pursue legal action:

• You reported symptoms (such as a lump or breast pain) but were not referred for further tests.
• Your mammogram or scan was incorrectly reported as normal, when cancer was in fact present.
• A previous scan showing early signs of cancer was not reviewed or acted upon.
• You were told you had breast cancer when you did not, leading to unnecessary treatment.
• You were not offered the triple assessment (examination, imaging, biopsy) when presenting with symptoms.

Compensation in Breast Cancer Misdiagnosis Claims

If your breast cancer was diagnosed late or incorrectly, and that failure caused avoidable harm, you may be entitled to compensation. The purpose of compensation is not only to acknowledge what went wrong—it’s to help restore stability in the aftermath of serious medical error. In Ireland, damages in medical negligence cases are awarded under two broad headings: general damages and special damages.

General Damages

This covers the non-financial impact of the negligence:

• Pain and suffering caused by more invasive treatment than was necessary
• Emotional distress from being misdiagnosed or falsely reassured
• Reduced quality of life or permanent injury
• Loss of fertility, scarring, or psychological trauma from unnecessary surgery or treatment

General damages are assessed based on the severity and duration of the harm suffered. The Personal Injuries Guidelines published by the Judicial Council are used as a reference, though medical negligence cases are typically more complex than standard personal injuries claims.

Special Damages

These cover the financial costs or losses arising from the negligence:

• Loss of earnings (including future loss if you can’t return to work)
• Medical costs such as private scans, second opinions, or corrective procedures
• Travel and accommodation for out-of-town treatments
• Home care, childcare, or specialised support services during recovery

Where a loved one has died due to a missed or late diagnosis, families may also claim for loss of financial dependency, funeral expenses, and the deceased’s pain and suffering up to the time of death.

How Compensation Is Calculated

Each case is assessed individually. Compensation depends on factors like:

• The length of the diagnostic delay
• How much the error changed the outcome
• The physical and psychological toll of additional or unnecessary treatment
• The long-term impact on your life, income, and future care needs

The process is expert-led, and Crimmins Howard works with independent medical specialists, forensic accountants and legal counsel to ensure your claim reflects the full extent of the harm caused.

Support and Resources for Patients and Families

Coping with the aftermath of a breast cancer misdiagnosis is overwhelming—not just medically, but emotionally and practically. Alongside legal advice, many people need clear, reliable support. Below are trusted Irish resources for patients and families:

• Irish Cancer Society: Offers information on treatment, counselling, peer support, and financial guidance.
• BreastCheck: Ireland’s national breast screening programme. You can request copies of your screening records and imaging if you suspect an error occurred. 
• Citizens Information: Provides guidance on medical cards, hospital complaints procedures, and your rights under the Health Act.
• Bereavement and Inquest Support (via Coroner Service): If a death occurred following misdiagnosis, the Coroner’s Court may open an inquest. We can guide families through this legal process while connecting them to practical supports.

These services complement legal action, and we’re happy to help you access them.
